5. Automating Tasks with Macros:
   • Macros are created using the Macro Design View. Users can choose from a set of predefined actions or create custom macros to automate tasks. Macros streamline processes, enhance user interaction, and improve overall database efficiency.
6. Extending Functionality with Modules:
   • Modules accommodate VBA code and are accessed through the Module Design View. Advanced users can write custom scripts, procedures, and functions to extend the functionality of their database beyond the capabilities of standard Access features.

Object Relationships in MS Access 2016:

1. Table Relationships:
   • Establishing relationships between tables is crucial for maintaining data integrity and facilitating efficient data retrieval. Relationships define how records in one table relate to records in another, creating a cohesive structure for the database.
2. Referential Integrity:
   • Referential integrity ensures that relationships between tables are maintained. It prevents the creation of orphaned records by enforcing that a record in one table must have a corresponding record in another table.
3. Enforcing Cascade Options:
   • MS Access allows users to define cascade options for relationships, specifying how changes to records in one table affect related records in another. Cascade options include updates and deletes, providing flexibility in managing data consistency.

Practical Applications of MS Access Objects:

1. Data Management in Businesses:
   • MS Access objects find extensive use in businesses for managing customer data, inventory, and project information. The relational database model and the flexibility of objects make MS Access a valuable tool for organizing and analyzing business data.
